I thought they'd improved the seat for 2022 vs the old 2017-2021 seats. My 2017 seats were fairly terrible, there is zero padding on the sides so dug into my ribs, I added foam padding and that went fairly well, possibly you could do the same on your 2023 and not have to worry about the wiring issues?

Do you have a Volt handy you could check the signals coming from it's module vs what the Bolt's module is putting out? I mean if there's the same amount of wires it's odd that it would act too differently at that point as it should be fairly analog.

....The only thing I can really think of off hand is if, for example, the Volt heat has different resistance than the Bolt heater and THAT'S what measured by the Control Module. That's a total guess, but there aren't any temperature sensors in the seat, and for safety at a minimum, the car needs some way to monitor it.

Do you still have the old Bolt seat? I'm wondering if you could just pull the upholstery from each seat and swap the elements/wiring from the Bolt one to the Volt one? When I redid the padding on my Bolt the seat cover popped off fairly easy compared to older car seats, and the heater elements were directly underneath the upholstery.

I agree the heated seat is really comfy, come a long way since the old vinyl seats I'd have to endure as a kid in New England lol.
